Smart Table Loader is a lightweight, browser-based tool that lets you upload and display CSV, Excel (.xls/.xlsx), or JSON files in a dynamic and interactive HTML table powered by DataTables.js. This tool is great for quick data analysis without the need for installing heavy software.

Demo: https://basemax.github.io/smart-table-loader/

• Upload .csv, .xls, .xlsx, or .json files
• Automatic detection and sanitization of table headers
• DataTables integration with:
  • Column visibility toggling
  • Export to Excel, CSV, Copy
  • Responsive and scrollable tables
  • State saving (remembers table settings)
• File info display before rendering
• Minimal and clean UI using Google Fonts

Clone the repository and open index.html in any modern web browser:

git clone https://github.com/BaseMax/smart-table-loader.git cd smart-table-loader open index.html # or double-click to open in browser

1. Open index.html in your browser.
2. Click on the "Upload" field and select a CSV, Excel, or JSON file.
3. View your data rendered in a feature-rich HTML table.

Use CSVLint.io to validate your CSV files before uploading.

This project uses:

• PapaParse (for parsing CSV)
• SheetJS (xlsx) (for Excel)
• DataTables and extensions

This project is inspired by csv-to-html-table, and I have enhanced it with many additional features.
